Answer:
DA/dt = 37 / 18
Step-by-step explanation:
We have the following information:
Sides of the rectangle L = length w = width
Area of the rectangle is : A = L* w
the rate of growing of the length ( as function of time ) 1 mile in 6 years
we can express that as :
DL/dt = 1 /6
And the rate of growing of the width ( as function of time ) 1 mile in 9 years
Dw/dt = 1/9
In 1995 dimensions of the rectangle were
L = 5 miles and w = 9 miles
Then:
A = L * w Taking derivatives
DA/dt = L * Dw/dt + w * DL/dt
DA/dt = 5 * (1/9) + 9 * (1/6) ⇒ DA/dt = 5/9 + 9/6
DA/dt = 111 / 54 ⇒ DA/dt = 37 / 18
I believe the answer is 100 milliliters
Answer:
5
Step-by-step explanation:
First, ad 4 and 3 together. You get 7. Then, subtract 7 from 14. You get 7. Then subtract 2 from 7, and your final answer should be 5.
